The Histogenesis of Basement Membranes
A parietal yolk sac carcinoma of the mouse that secretes large quantities of basement membrane-like material has been used to study the formation of basement membranes. Suitably characterized fluorescein-labeled antibodies against this material stained basement membranes of epithelial structures and vessels, as well as reticulin. When absorbed with reticulin and vascular basement membranes of t...
متن کاملThe Histogenesis of Primary Hepatic
The existence of hepatocellular and cholangiocellular carcinomata, arising from liver cells and bile duct epithelium respectively, has long been recognized, although the proportions of each type have varied in different series. Gustafson (1937) reported 39 liver cell and 11 bile duct tumours amongst 62 cases of primary liver carcinoma based on 24,400 necropsies, and Wilbur, Wood, and Willett (1...
متن کاملThe Histogenesis of Blood Platelets
1. Under normal circumstances blood platelets are largely derived from the megakaryocyte of the blood-forming organs. 2. The transitional leucocyte, representing a persistent form of the embryonic premegakaryocyte, is a circulating homologue of the megakaryocyte and probably plays some part in normal platelet formation. 3. Under conditions of excessive demand for platelet production, there may ...
متن کاملGyrate Atrophy of the Choroid and Retina: A Case Report
Introduction Gyrate atrophy of the choroid and retina is a metabolic disorder, which is inherited in an autosomal recessive pattern. Although gyrate atrophy is rare, it is concerning as it results in blindness. It is characterized by hyperornithinemia, retinal atrophy, leads to progressive myopia and tunnel vision,...
متن کاملModels of epithelial histogenesis.
Epithelial tissues emerge from coordinated sequences of cell renewal, specialization and assembly. Like corresponding immature tissues, adult epithelial tissues are provided by stem cells which are responsible for tissue homeostasis. Advances in epithelial histogenesis has permitted to clarify several aspects related to stem cell identification and dynamics and to understand how stem cells inte...
